A man wouldn’t leave an overbooked United flight. So he was dragged off, battered and limp.

United Airlines says a man wouldn’t give up his spot on an overbooked flight Sunday.

So, according to witnesses and videos of the incident, he was pulled screaming from his seat by security, knocked against an arm rest and dragged down the aisle and back to the terminal at Chicago’s O’Hare International Airport.

United refused to answer questions about the incident, which horrified other passengers on the Louisville-bound flight. An airline spokesman only apologized for the overbooked flight, and said police were called after a passenger “refused to leave the aircraft voluntarily.”

What happened was captured on cellphone video by at least two passengers.

Tyler Bridges recalled trouble starting almost as soon as he and his wife boarded.

An airline supervisor walked onto the plane and brusquely announced: “We have United employees that need to fly to Louisville tonight. … This flight’s not leaving until four people get off.”

In another video, the man runs back onto the plane, his clothes still mussed from his forcible ejection, frantically repeating: “I have to go home. I have to go home.”

“He was kind of dazed and confused,” Bridges said. He recalled a group of high school students leaving the plane in disgust at that point, their adult escort explaining to other passengers: “They don’t need to see this anymore.”

The airline eventually cleared everyone from the plane, Bridges said, and did not let them back on until the man was removed a second time — in a stretcher.

In the end, Bridges and his wife got to Louisville about three hours late.

“It was a pretty tense flight,” he said.

United Chief Oscar Munoz tweeted that everyone at the airline was upset about it.

Munoz, by the way, was recently honored as “Communicator of the Year” by PRWeek. Late Monday afternoon, the Chicago Department of Aviation said one of the officers involved in the incident had been placed on leave.

“The incident on United flight 3411 was not in accordance with our standard operating procedure and the actions of the aviation security officer are obviously not condoned by the Department,” the agency said in a statement. “That officer has been placed on leave effective today pending a thorough review of the situation.”
